Cost calculator
Cost per labeled amount
See what a particular amount of an ingredient costs. Comparing a second product is optional.
This is a cost calculation. It does not judge product quality or suitability.
Questions
Is a lower cost per milligram a better product?
No. The page only divides the presented price by the servings and the labeled amount you enter.
When can two products be compared?
Only when the ingredient, the unit, and the currency match. Otherwise the page does not compare them.
How this number is made
What this result means
The result is the presented price divided by the servings and by the labeled amount you type. The 30-day figure is an estimated consumption cost. It is not the price of the next bottle, and it is not a cost per effective dose.
Formula and methodology
Cost per labeled unit is the container price divided by the servings and by the amount in one serving. The 30-day estimate uses the same full-precision per-serving cost as Price per serving. A second product is shown beside the first only when the ingredient, the unit, and the currency match.
Worked example
A container priced at 30 with 60 servings and 200 mg in each serving costs 0.50 per serving. The cost per milligram is 30 divided by 12,000. The same container used daily has an estimated 30-day consumption cost of 15.00.
Assumptions and limitations
The labeled amount is the figure you type from Supplement Facts, such as elemental magnesium, not the weight of the compound. A capsule count is not entered here as a serving count. Shipping, tax, and conditional coupons are outside the figure unless they are already in the presented price. Currencies are not converted. A lower cost per milligram is not a better supplement.
Who should not rely on the result
Anyone who wants this number to decide whether a supplement works, or who needs the retailer's own quote, should not treat the result as that decision.
